MAT.

To all whom it may concern:

Be it known that I, JnNs PETER LARSEN, a subject of the King of Denmark,whose residence is VVoodmere, Long Island, county of Nassau and State ofNew York, have invented certain new and useful Improvements in Mats, ofwhich the following is a specification.

This invention relates to mats and has for its object to provide a matof inexpensive construction, which is more practical and sanitary thanany of the kind heretofore known or now commonly used.

Another object of the invention is to provide a mat which will prove oflong durability, as the parts mainly exposed to wear and tear may besubstituted and renewed.

lVith the above and other objects in view, the invention consists of thenovel features of construction, combination and arrangement of partshereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which Figure 1 is a plan view of a matconstructed in accordance with the present invention; Fig. 2 is atransverse section taken on line a a of Fig. 1; Fig. 3 is a front elevation with a part of the front rail, or frame, broken away in order toshow more clearly the construction and arrangement of parts; Fig. 4t andFig. 5 are detail sectional views.

Referring in detail to the drawings, my invention comprises a preferablyrectangular frame having two side bars, or members and two shorter crossbars, or members 11. The ends of these frame bars are detachablyconnected by clamps, comprising two sections one of which 12 is rigidlysecured. to the ends of the side bars, while the other section 13 isrigidly secured to the cross bars at their outer edges and adapted toreceive the former, which has a projecting hook fitting the latter whenjoined together: said clamps are secured to the frame members by meansof screws.

It is obvious that said frame lnen'd'iers may be connected in differentways such as by means of hinges, screws, etc.

The frame members 11 are at a small distance from their upper edgesprovided with a plurality of transverse holes 14 adapted to receive thereduced outer ends of a num- Application filed July 9, 1924. Serial No.725,021.

ber of rollers 15 so as to permit a free rotative movement of saidrollers.

The rollers are of a cylindrical shape and they have reduced endportions in case that a ball bearing should be decided upon tofacilitate the rotative movement of such rollers.

Upon said rollers are mounted a number of cylindrical rubber tubes 16 ofa comparatively hard quality; said rubber tubes being of a rather shortlength as indicated at 16 to permit the replacement of any one that hasbeen worn out or damaged. The outer side of these rubber tubesv may bepro-. vided with a corrugated or uneven surface to make the scrapingmore effective.

While a close fitting of the rubber tubes with the roller is provided,there is mounted on both end pieces of said rollers between the rubbertubes and the side bars washers 17 to prevent any displacement of saidrubber tubes and to secure a smooth run of said rollers in the holes ofthe side bars.

This mat has below as a bottom part a drawer or scuttle 18, while oneside bar has its lower front part cut away as indicated at 19 to permitthe insertion of such drawer.

The drawer 18 has a bottom 20; a backwall 21 and sidewalls 22: at theupper edge of said sidewalls are rigidly secured to these, at a rightangle, flanges 23 adapted to slide in transverse grooves, provided inthe side frames, as indicated at 24, to secure a steady movement of suchdrawer. The front-wall 25 of said drawer, closes up the reduced portionof the side bar, thereby giving said frame a finished appearance. Tohold said drawer in closed position, a turn-strip 26 is secured by ascrew to the upper part of the front or side bar.

To impart steadiness to such mat, there is secured below each end of theside bars, a. small rubber patch or footing 27..

While I have shown and described the preferred construction andarrangement of the several elements employed, I reserve the privilege ofresorting to all such legitimate changes as may be fairly embodiedwithin the spirit and scope of the appended claim ;--furthermore it isobvious that my invention may be made of any suitable ma terial, such aswood, steel, etc, and instead of rubber, may be employed bristles, thining reduced outer ends journalled in the 10 Wires, etc. end bars of saidframe, a plurality of cylin- Having thus fully described my inven dricalelastic bodies having corrugated outer tion, I claim as new and desireto secure by faces mounted end to end on each of said 5 Letters Patentrollers, means for preventing lon itudinal A mat comprising asubstantially recdisplacement of said bodies on sai rollers, 1 tangularframe, a means for detachably and cushioning means for said frame.
